POV parking (long term) near Las Vegas and Seattle

I am planning a long adventure to the west and would like to leave my POV (which I load with camping equipment) at military facilities near Las Vegas airport and also near Seattle airport. Has anyone got any advice? Thanks

You didn't say how long you wanted to place your rig in storage so I am guessing maybe a month or more.
In Vegas, if you want it back the same way you left it, you might be able to put it in the long term storage lot at Nellis AFB, the FamCamp has a "short term" lot that may work out. The long term lot used to have a waiting list, don't know about it now.
Nellis is not real close to the airport, but public transportation is available.
You should be able to find out about storage by calling the FamCamp office, at least they should be able to guide you in the right direction.
